To meet the demands of the casual and competitive sportsperson, much study and growth has been done by the sun wear manufacturers as to how they could create the best sunglasses for various activities, requirements and environments. The results: lightweight, flexible and durable materials, no-slip components that do not fail in the heat of the moment, and of course lenses were introduced. Lenses Lenses, perhaps the main significant aspect effective for sports sun wear has optical quality and image enhancement. These lenses are now accessible in many colors such as brown, green, gray, yellow, orange, etc… that are chiefly effective in certain situations. Polycarbonate lenses are tremendously popular for its super muscular and impact-resistant quality that particularly attracts many people involved in sports. Polarized lenses are also in great demand as they decrease glare produced on smooth surfaces such as water or a field of snow. Polarized lenses are highly effective sports lenses that work effectively with both the contradictory sports activities like the downhill to mogul skiing. Glass lenses have great visual quality. Hence they are used as casual sunglasses and for golfing. Even though glass lenses have such great visual quality they are rarely used as sports eyewear because many people concerned in extreme sports shy away from glasses lenses for the possibility of shattering upon impact. What's Your Sport? One major trend that has hit the sports eyewear arena lately is sports-specific sun wear. Frames and lenses are now accessible that are targeted exclusively to the golfer, the cyclist, the boater, the rock climber and so on. This accessibility and specialization has fashioned great consumer interest and hence has increased sales in sports eyewear. If you are the Jack of all sports, there is also a selection of multipurpose sports sunglasses available for you in the market. Changeable lens systems are also obtainable. Another tendency in sports eyewear that has made consumers much more conscious of the brands and the products out there are the product endorsements and sponsorships by well-known professional athletes. Kobe Bryant of the Los Angeles Lakers, John McEnroe of pro tennis fame, PGA golfer David Ledbetter, Missy Giove, a top mountain biker, pro surfer Laird Hamilton, and even Olympic skier Johnny Moseley all have support deals with chief sports eyewear lines.
